lycopenes
:
vitamin-like antioxidants that help prevent damage to DNA and may help lower prostate cancer risk. These substances are found in tomatoes, grapefruit, and watermelon.
lymph
(limf)
:
clear fluid that flows through the lymphatic vessels and contains cells known as lymphocytes. These cells are important in fighting infections and may also have a role in fighting cancer.
lymph nodes
:
small bean-shaped collections of immune system tissue such as lymphocytes, found along lymphatic vessels. They remove cell waste and fluids from lymph. They help fight infections and also have a role in fighting cancer. Also called lymph glands.
lymphadenectomy
:
surgical removal of lymph nodes. After removal, the lymph nodes are examined by microscope to see if cancer has spread; also called lymph node dissection.
lymphatic system
:
the tissues and organs (including lymph nodes, spleen, thymus, and bone marrow) that produce and store lymphocytes (cells that fight infection) and the channels that carry the lymph fluid. The entire lymphatic system is an important part of the body's immune system. Invasive cancers sometimes penetrate the lymphatic vessels (channels) and spread (metastasize) to lymph nodes.
lymphedema
(limf-uh-dee-muh)
:
A complication that sometimes happens after breast cancer treatments. Swelling in the arm is caused by excess fluid that collects after lymph nodes and vessels are removed by surgery or treated by radiation. This condition can be persistent but not painful.
lymphocytes
:
a type of white blood cell that helps the body fight infection.
lymphocytosis
(limf-o-sigh-toe-sis)
:
having an excess of lymphocytes.
lymphokines
(limf-o-kines)
:
See cytokine
lymphoma
(lim-foam-uh)
:
cancer of a type of white blood cells called lymphocytes. Lymphoma usually starts in lymph nodes, but less often can develop in organs of the digestive system.
